This invention relates to improvements in hopper dump cars.

ln the well-known inl-type of hopper car, it has been4 customary heretofore to employ a transversely extending ridge at the center of the car between the sets of hopper doors,

said ridge projecting upwardly into the body of the car and therebyy reducing the load-carrying capabity of the car. lf the angle of sa-id ridge is left comparatively obtuse, for the purpose of minimizing the Waste space, then dimculty is encountered in properly discharging the load. @n the contrary, if the angle of ysaid ridge is made acute to insure proper discharge of the load, the capacity of the car is reduced and also the center of gravity of the load is made higher.

3@ An object of my invention is to provide,

in a hopper car of the generellen-called lill-type, increased. load-carrying capacity without an increase of theI over-all dimensions as compared with the standard lill-type f hopper proper, or, stated in another manner, obtain the saine carryingcapacity with lesser over-all dimensions. i f

Another object of my invention is to pro-- vide a car of the type indicated in the preceding paragraph wherein the arrangement for obtaining the increased capacity is utilined without interference in the full opening of the usual end hopper doors;y Without appreciable additional cost; and with full 'assurance of discharge 'of 100% of the load.

My/invention further resides vin certain otherl features of novelty 'and construction `such as"will more clearl appear from the ,description and claims ollowing,` I

' ln. the drawings forming` a part of this specification, Figure l is a side elevational 'Viewl ofv slightly more than one-half `of a hopper car embodyingmy improvements. Figure 2 is a fragmentary, vertical, transverse sectional view taken on a line corresponding substantially to line 2--2 of Figure 1. Figure 3 4is a vertical transverse sectional view on the line 3-3 of Figure l upon an enlarged scale, the lefthand half vside thereof illustrating the corresponding intermediate hopper door in closed position and the righthand half illustrating the righthand intermediate hopper door in open position. L I ln said drawings, the side walls of the car .are indicated by the reference charactor-it; a sloping end floor by the reference character B; and the center sill by the reference character C. As clearly shown, in Figure l, the hopper car is provided with `a longitudinal series of three hoppers on each side of the car, the two end hoppers being designated ,d generally ,by reference characters .DL-D andthe intermediate hopper by the'reference haracter E. ln Figure'ly of the drawing, it will be noted that l have indicated in dotted lines the usual arrangement of transverse ridge iF employed in the common lill-type hopper car. ln carrying out my invention, this ridge l@ 'is entirely omitted and the two hoppers E employed in lieu thereof with consequent increase in load-carryin capacity, the hopperslll being disposed ietween the transverse cross members Gr. f

Each of said end hoppers D, on each side of the center sill, is dehned by the lower portion of a sloping end floor B; an inner, substantially triangular side hopper sheet l@ secured to the center sill; -an outer, inwardly sloping side hopper sheet il; and a transversely extending ridge sheet 12, the latter being secured along' its upper edge to a vertically disposed transverse plate 13 of crossbeam G. lilach sloping end floor B is referably suitably reinforced at its bottom ree edge by an angle iron it and similarly the bottom edge of each ridge sheet '12 is reinforced'by an angle iron l5 Isecured to the underside thereof and braced to the needlebeam i3 by means of braces i6. 'lo each transverse -ridge l2 is pivotally attached, along its upper edge, a transversely extending end hopper door 17. lli-eferably,v each pair' of transversely aligned end hopper doors 17 is rigidly connected by -suitable bracing as indicated at 1.8 so that the same may be operated simultaneously by means of ,suitable door operating mechanism actuated' from the'corresponding adjacent shaft 19. Said operating mechanism preferably' cqnsists of an arm 20, rigidlysecured to shaft 19, and connected to the door bracing 18 by means of link 2On with the parts so associated that the operatving mechanism will serve to maintain the doors in open position as indicated inv Fig ure f 1.

The crossbeams Gr, wlich extend transverse-ly of the car from side to side thereof, are suitably spaced from each other as indiclated in Fig. 1 for the purpose of accommodating the intermediate hoppers E therebetween, said hoppers E being disposed one on each side of the center sill. Each of said intermediate hoppers E is defined by means of transversely extending ridge plates 21-21 riveted to the corresponding vertically disposed-'plates 13 of crossbeams AGr, outer hopper sheets 22, and inne-r hopper sheet 23, the latter forming a ridge extending longitudinally over the center sill. Intermediate the crossbeams G, the ridge sheets 23 lare supported from the center sill bykmeans of brackets 24 and the lower edges of the ridge sheets 23 are reinforced by longitudinally extendingA angles 25 which are fitted with suitable hinge butts 26. On the hinge butts 26, doors 27 are swingingly mounted and adapted to close with the free edges thereof [adjacent the sides of the car.

The lower edge of each outer hopper sheet- 22 is reinforced by means of a reinforcing strip 28 which insures a tight joint for the door at the flee edge thereof. The free edge of each door is supported in closed position by means of door supporting hooks 29 which engage brackets 30 projecting beyond the free ledge of the door. Two hooks per door are preferably used and these, for purposes of economy, are preferably mounted on the same bracket 31 which is extended from one to the other and secured to the outer hopper sheet 22. A cam 32 is mounted on the bracket 31 adjacent each hook 29 ment with the door.

and is adapted to engage the same to prev enough, would strike the doors 17 when the latter are open. In order to limit the downward swing of the door 27 and prevent the same from hitting on the end hopper doors, a stop 33 is provided. Said stop 33 preferably consists of a plate or other structural member bent to a U-shape and secured to the vertical plates 13 of the crossbeam G.

Each cmssbearn G has the lower part thereofl formed of a plurality of sections of angle, secured on opposite sides of the plate 13 and adapted to overlap for a limited distance. Angle 34, forming the inner portion 'the car.

of the crossbeam bottom member, is so disposed that the horizontal flange of the angle is below the vertical flange thereof whereas the section of angle 35, forming the outer portion of the crossbeam member, is so disposed that the horizontal flange of the angle is above the vertical flange thereof. The usual bottom cover plate 36 extends :across the plane of the center sill and on either side thereof and is there secured to the horizontal flanges of the angles 3ft-34:. The upper margin of each vertical plate 13 is stifene'd by means of an angle 37 secured thereto and extending transversely through Side stakes 38, each secured to one end of the crossbeam G and side A of the car, prevent outward bulging of the sides.

lVith my arrangement of two end hoppers and an intermediate dumping space in the manner shown Iam enabled to secure greater load carrying capacity than has heretofore been secured with this type of car and this while still permitting the unloading of the car in bins of the same length as heretofore, inasmuch as the dumping of the load is concentrated between the two end hoppers as heretofore. While Idiave shown and described my improvements in connection with a. standard hopper car and the advantages of the same in connection therewith will be readily seen, it will be apparent that in certain circumstances, it might be advantageous to lengthen the car and increase the width of the intermediate hopper and dispose a dumping door of greater width or a plurality of doors, oper- .ated singly or in unison by means 'of power mechanism, might be used.

lVhilc l have shown and described what l now consider the preferred manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
